Late onset rheumatoid arthritis associated with interstitial lung disease

摘要

Rheumatoid arthritis of late onset occurs in the population over 65 years of age, presenting differences in clinical and laboratory manifestations compared to rheumatoid arthritis in younger people, with a higher risk of presenting with aggressive forms of the disease, and with systemic compromise. The presence of a probable relationship between the interstitial lung disease associated with late-onset rheumatoid arthritis is established in this case. In most cases pulmonary involvement occurs after the joint problems, although they may appear simultaneously, and may even be the first manifestation. Pathological findings in interstitial pneumonias associated with collagen diseases are similar to idiopathic interstitial pneumonias. A case is presented of a woman who had pulmonary involvement due to idiopathic interstitial pneumonia, and subsequently presented with joint pain with rheumatoid arthritis being documented.
